About CircuitKitchen
CircuitKitchen is a collection of practical calculators for circuit design.
Circuit design involves more than finding a nominal value. Component tolerances, loading, and operating conditions affect how a circuit performs. CircuitKitchen brings calculations, comparisons, and explanations together so you can check a component value, explore alternatives, and see how design choices affect the results.

Brad Claflin is an electrical engineer and founder of Technology Kitchen, a product development company he has led for 18 years. He has approximately 37 years of practical experience in circuit design and product development, including aircraft and UAV products, LED lighting, industrial controls, test fixtures, semiconductor manufacturing equipment, and consumer products.
CircuitKitchen grew from spreadsheet calculators Brad created for himself and his engineering team and refined over many years. Those spreadsheets supported tolerance analysis and power calculations. CircuitKitchen builds on that foundation to help users select standard component values, understand design tradeoffs, and compare alternatives through detailed calculations.
Brad is responsible for the calculators’ engineering equations, assumptions, and results. He has personally checked all seven published calculators, using his original spreadsheets and hand calculations to verify their results.
CircuitKitchen helps you check component markings, select practical resistor values, and evaluate circuit performance. Visit the homepage to see what you can do and how to understand the results.
